The heat-insulating, fire-proof, water-resistant, permeable-to-air, flexible lightweight concrete with a volume-density below 500 kg/m 3 , made with polystyrene pearl according to the invention is equally suitable for heat-, and sound-insulation of walls and slabs, as well as decreasing their water permeability or water-absorbing capacity, as well as increasing their resistance to fire at the same time keeping their ability to be permeable-to-air and humidity, for renovation old buildings or building new buildings. Its composition is: polystyrene pearl, or recycled polystyrene of 1-10 mm diameter, water, cement and organic (polymer) binding material mixed with cement: such homo-, co-, and terpolymers - which are water-soluble and/or can be dispersed in water. Resulting from the use of organic (polymer) binding material, the polystyrene pearls can be easily mixed with the inorganic binding material and water. The heat-insulating material produced this way can be even 100 kg/m 3 , depending on the quantity of the binding materials. The ready-made material can be greased, pumped, cast; board, brick or filling walls can be made of it, and above 300 kg/m 3 volume density it can be plastered as well. The cement can be mixed or replaced by gypsum. The polystyrene pearl can be mixed, or replaced by a material, which consists of granules and is water-repellent and is of small volume-density (max. 400 kg/m 3 ).
